11d80a6a38 Optimise per_epoch_processing low-hanging-fruit (#3254)
## Issue Addressed

NA

## Proposed Changes

- Uses a `Vec` in `SingleEpochParticipationCache` rather than `HashMap` to speed up processing times at the cost of memory usage.
- Cache the result of `integer_sqrt` rather than recomputing for each validator.
- Cache `state.previous_epoch` rather than recomputing it for each validator.

### Benchmarks

cc4b778b1f Inline safe_arith methods (#3229)
## Proposed Changes

Speed up epoch processing by around 10% by inlining methods from the `safe_arith` crate.

The Rust standard library uses `#[inline]` for the `checked_` functions that we're wrapping, so it makes sense for us to inline them too.

## Additional Info

I conducted a brief statistical test on the block at slot [3858336](https://beaconcha.in/block/3858336) applied to the state at slot 3858335, which requires an epoch transition. The command used for testing was:

```
lcli transition-blocks --testnet-dir ./common/eth2_network_config/built_in_network_configs/mainnet --no-signature-verification state.ssz block.ssz output.ssz
``` 

The testing found that inlining reduced the epoch transition time from 398ms to 359ms, a reduction of 9.77%, which was found to be statistically significant with a two-tailed t-test (p < 0.01). Data and intermediate calculations can be found here: https://docs.google.com/spreadsheets/d/1tlf3eFjz3dcXeb9XVOn21953uYpc9RdQapPtcHGH1PY

bcdd960ab1 Separate execution payloads in the DB (#3157)
## Proposed Changes

Reduce post-merge disk usage by not storing finalized execution payloads in Lighthouse's database.

⚠️ **This is achieved in a backwards-incompatible way for networks that have already merged** ⚠️. Kiln users and shadow fork enjoyers will be unable to downgrade after running the code from this PR. The upgrade migration may take several minutes to run, and can't be aborted after it begins.

The main changes are:

- New column in the database called `ExecPayload`, keyed by beacon block root.
- The `BeaconBlock` column now stores blinded blocks only.
- Lots of places that previously used full blocks now use blinded blocks, e.g. analytics APIs, block replay in the DB, etc.
- On finalization:
    - `prune_abanonded_forks` deletes non-canonical payloads whilst deleting non-canonical blocks.
    - `migrate_db` deletes finalized canonical payloads whilst deleting finalized states.
- Conversions between blinded and full blocks are implemented in a compositional way, duplicating some work from Sean's PR #3134.
- The execution layer has a new `get_payload_by_block_hash` method that reconstructs a payload using the EE's `eth_getBlockByHash` call.
   - I've tested manually that it works on Kiln, using Geth and Nethermind.
   - This isn't necessarily the most efficient method, and new engine APIs are being discussed to improve this: https://github.com/ethereum/execution-apis/pull/146.
   - We're depending on the `ethers` master branch, due to lots of recent changes. We're also using a workaround for https://github.com/gakonst/ethers-rs/issues/1134.
- Payload reconstruction is used in the HTTP API via `BeaconChain::get_block`, which is now `async`. Due to the `async` fn, the `blocking_json` wrapper has been removed.
- Payload reconstruction is used in network RPC to serve blocks-by-{root,range} responses. Here the `async` adjustment is messier, although I think I've managed to come up with a reasonable compromise: the handlers take the `SendOnDrop` by value so that they can drop it on _task completion_ (after the `fn` returns). Still, this is introducing disk reads onto core executor threads, which may have a negative performance impact (thoughts appreciated).

## Additional Info

- [x] For performance it would be great to remove the cloning of full blocks when converting them to blinded blocks to write to disk. I'm going to experiment with a `put_block` API that takes the block by value, breaks it into a blinded block and a payload, stores the blinded block, and then re-assembles the full block for the caller.
- [x] We should measure the latency of blocks-by-root and blocks-by-range responses.
- [x] We should add integration tests that stress the payload reconstruction (basic tests done, issue for more extensive tests: https://github.com/sigp/lighthouse/issues/3159)
- [x] We should (manually) test the schema v9 migration from several prior versions, particularly as blocks have changed on disk and some migrations rely on being able to load blocks.

b49b4291a3 Disallow attesting to optimistic head (#3140)
## Issue Addressed

NA

## Proposed Changes

Disallow the production of attestations and retrieval of unaggregated attestations when they reference an optimistic head. Add tests to this end.

I also moved `BeaconChain::produce_unaggregated_attestation_for_block` to the `BeaconChainHarness`. It was only being used during tests, so it's nice to stop pretending it's production code. I also needed something that could produce attestations to optimistic blocks in order to simulate scenarios where the justified checkpoint is determined invalid (if no one would attest to an optimistic block, we could never justify it and then flip it to invalid).

4d0122444b Update and consolidate dependencies (#3136)
## Proposed Changes

I did some gardening 🌳 in our dependency tree:

- Remove duplicate versions of `warp` (git vs patch)
- Remove duplicate versions of lots of small deps: `cpufeatures`, `ethabi`, `ethereum-types`, `bitvec`, `nix`, `libsecp256k1`.
- Update MDBX (should resolve #3028). I tested and Lighthouse compiles on Windows 11 now.
- Restore `psutil` back to upstream
- Make some progress updating everything to rand 0.8. There are a few crates stuck on 0.7.

Hopefully this puts us on a better footing for future `cargo audit` issues, and improves compile times slightly.

## Additional Info

Some crates are held back by issues with `zeroize`. libp2p-noise depends on [`chacha20poly1305`](https://crates.io/crates/chacha20poly1305) which depends on zeroize < v1.5, and we can only have one version of zeroize because it's post 1.0 (see https://github.com/rust-lang/cargo/issues/6584). The latest version of `zeroize` is v1.5.4, which is used by the new versions of many other crates (e.g. `num-bigint-dig`). Once a new version of chacha20poly1305 is released we can update libp2p-noise and upgrade everything to the latest `zeroize` version.

I've also opened a PR to `blst` related to zeroize: https://github.com/supranational/blst/pull/111

414197b06d Enable proposer boost on mainnet and GBC (#3131)
## Proposed Changes

Mitigate the fork choice attacks described in [_Three Attacks on Proof-of-Stake Ethereum_](https://arxiv.org/abs/2110.10086) by enabling proposer boost @ 70% on mainnet.

Proposer boost has been running with stability on Prater for a few months now, and is safe to roll out gradually on mainnet. I'll argue that the financial impact of rolling out gradually is also minimal.

Consider how a proposer-boosted validator handles two types of re-orgs:

## Ex ante re-org (from the paper)

In the mitigated attack, a malicious proposer releases their block at slot `n + 1` late so that it re-orgs the block at the slot _after_  them (at slot `n + 2`). Non-boosting validators will follow this re-org and vote for block `n + 1` in slot `n + 2`. Boosted validators will vote for `n + 2`. If the boosting validators are outnumbered, there'll be a re-org to the malicious block from `n + 1` and validators applying the boost will have their slot `n + 2` attestations miss head (and target on an epoch boundary). Note that all the attesters from slot `n + 1` are doomed to lose their head vote rewards, but this is the same regardless of boosting.

Therefore, Lighthouse nodes stand to miss slightly more head votes than other nodes if they are in the minority while applying the proposer boost. Once the proposer boost nodes gain a majority, this trend reverses.

## Ex post re-org (using the boost)

The other type of re-org is an ex post re-org using the strategy described here: https://github.com/sigp/lighthouse/pull/2860. With this strategy, boosted nodes will follow the attempted re-org and again lose a head vote if the re-org is unsuccessful. Once boosting is widely adopted, the re-orgs will succeed and the non-boosting validators will lose out.

I don't think there are (m)any validators applying this strategy, because it is irrational to attempt it before boosting is widely adopted. Therefore I think we can safely ignore this possibility.

## Risk Assessment

From observing re-orgs on mainnet I don't think ex ante re-orgs are very common. I've observed around 1 per day for the last month on my node (see: https://gist.github.com/michaelsproul/3b2142fa8fe0ff767c16553f96959e8c), compared to 2.5 ex post re-orgs per day.

Given one extra slot per day where attesting will cause a missed head vote, each individual validator has a 1/32 chance of being assigned to that slot. So we have an increase of 1/32 missed head votes per validator per day in expectation. Given that we currently see ~7 head vote misses per validator per day due to late/missing blocks (and re-orgs), this represents only a (1/32)/7 = 0.45% increase in missed head votes in expectation. I believe this is so small that we shouldn't worry about it. Particularly as getting proposer boost deployed is good for network health and may enable us to drive down the number of late blocks over time (which will decrease head vote misses).

## TL;DR

Enable proposer boost now and release ASAP, as financial downside is a 0.45% increase in missed head votes until widespread adoption.

ea783360d3 Kiln mev boost (#3062)
## Issue Addressed

MEV boost compatibility

## Proposed Changes

See #2987

## Additional Info

This is blocked on the stabilization of a couple specs, [here](https://github.com/ethereum/beacon-APIs/pull/194) and [here](https://github.com/flashbots/mev-boost/pull/20).

Additional TODO's and outstanding questions

- [ ] MEV boost JWT Auth
- [ ] Will `builder_proposeBlindedBlock` return the revealed payload for the BN to propogate
- [ ] Should we remove `private-tx-proposals` flag and communicate BN <> VC with blinded blocks by default once these endpoints enter the beacon-API's repo? This simplifies merge transition logic.

e4fa7d906f Fix post-merge checkpoint sync (#3065)
## Issue Addressed

This address an issue which was preventing checkpoint-sync.

When the node starts from checkpoint sync, the head block and the finalized block are the same value. We did not respect this when sending a `forkchoiceUpdated` (fcU) call to the EL and were expecting fork choice to hold the *finalized ancestor of the head* and returning an error when it didn't.

This PR uses *only fork choice* for sending fcU updates. This is actually quite nice and avoids some atomicity issues between `chain.canonical_head` and `chain.fork_choice`. Now, whenever `chain.fork_choice.get_head` returns a value we also cache the values required for the next fcU call.

aea43b626b Rename random to prev_randao (#3040)
## Issue Addressed

As discussed on last-night's consensus call, the testnets next week will target the [Kiln Spec v2](https://hackmd.io/@n0ble/kiln-spec).

Presently, we support Kiln V1. V2 is backwards compatible, except for renaming `random` to `prev_randao` in:

- https://github.com/ethereum/execution-apis/pull/180
- https://github.com/ethereum/consensus-specs/pull/2835

With this PR we'll no longer be compatible with the existing Kintsugi and Kiln testnets, however we'll be ready for the testnets next week. I raised this breaking change in the call last night, we are all keen to move forward and break things.

We now target the [`merge-kiln-v2`](https://github.com/MariusVanDerWijden/go-ethereum/tree/merge-kiln-v2) branch for interop with Geth. This required adding the `--http.aauthport` to the tester to avoid a port conflict at startup.

### Changes to exec integration tests

There's some change in the `merge-kiln-v2` version of Geth that means it can't compile on a vanilla Github runner. Bumping the `go` version on the runner solved this issue.

Whilst addressing this, I refactored the `testing/execution_integration` crate to be a *binary* rather than a *library* with tests. This means that we don't need to run the `build.rs` and build Geth whenever someone runs `make lint` or `make test-release`. This is nice for everyday users, but it's also nice for CI so that we can have a specific runner for these tests and we don't need to ensure *all* runners support everything required to build all execution clients.

## More Info

- [x] ~~EF tests are failing since the rename has broken some tests that reference the old field name. I have been told there will be new tests released in the coming days (25/02/22 or 26/02/22).~~

27e83b888c Retrospective invalidation of exec. payloads for opt. sync (#2837)
## Issue Addressed

NA

## Proposed Changes

Adds the functionality to allow blocks to be validated/invalidated after their import as per the [optimistic sync spec](https://github.com/ethereum/consensus-specs/blob/dev/sync/optimistic.md#how-to-optimistically-import-blocks). This means:

- Updating `ProtoArray` to allow flipping the `execution_status` of ancestors/descendants based on payload validity updates.
- Creating separation between `execution_layer` and the `beacon_chain` by creating a `PayloadStatus` struct.
- Refactoring how the `execution_layer` selects a `PayloadStatus` from the multiple statuses returned from multiple EEs.
- Adding testing framework for optimistic imports.
- Add `ExecutionBlockHash(Hash256)` new-type struct to avoid confusion between *beacon block roots* and *execution payload hashes*.
- Add `merge` to [`FORKS`](c3a793fd73/Makefile (L17)) in the `Makefile` to ensure we test the beacon chain with merge settings.
    - Fix some tests here that were failing due to a missing execution layer.

da4ca024f1 Use SmallVec in Bitfield (#3025)
## Issue Addressed

Alternative to #2935

## Proposed Changes

Replace the `Vec<u8>` inside `Bitfield` with a `SmallVec<[u8; 32>`. This eliminates heap allocations for attestation bitfields until we reach 500K validators, at which point we can consider increasing `SMALLVEC_LEN` to 40 or 48.

While running Lighthouse under `heaptrack` I found that SSZ encoding and decoding of bitfields corresponded to 22% of all allocations by count. I've confirmed that with this change applied those allocations disappear entirely.

## Additional Info

We can win another 8 bytes of space by using `smallvec`'s [`union` feature](https://docs.rs/smallvec/1.8.0/smallvec/#union), although I might leave that for a future PR because I don't know how experimental that feature is and whether it uses some spicy `unsafe` blocks.

2f8531dc60 Update to consensus-specs v1.1.9 (#3016)
## Issue Addressed

Closes #3014

## Proposed Changes

- Rename `receipt_root` to `receipts_root`
- Rename `execute_payload` to `notify_new_payload`
   - This is slightly weird since we modify everything except the actual HTTP call to the engine API. That change is expected to be implemented in #2985 (cc @ethDreamer)
- Enable "random" tests for Bellatrix.

## Notes

This will break *partially* compatibility with Kintusgi testnets in order to gain compatibility with [Kiln](https://hackmd.io/@n0ble/kiln-spec) testnets. I think it will only break the BN APIs due to the `receipts_root` change, however it might have some other effects too.

- [x] Add all of the new endpoints from the standard API: GET, POST and DELETE.
- [x] Add a `validators.enabled` column to the slashing protection database to support atomic disable + export.
- [x] Add tests for all the common sequential accesses of the API
- [x] Add tests for interactions with remote signer validators
- [x] Add end-to-end tests for migration of validators from one VC to another
- [x] Implement the authentication scheme from the standard (token bearer auth)

## Additional Info

The `enabled` column in the validators SQL database is necessary to prevent a race condition when exporting slashing protection data. Without the slashing protection database having a way of knowing that a key has been disabled, a concurrent request to sign a message could insert a new record into the database. The `delete_concurrent_with_signing` test exercises this code path, and was indeed failing before the `enabled` column was added.

The validator client authentication has been modified from basic auth to bearer auth, with basic auth preserved for backwards compatibility.

ee000d5219 Native support for Gnosis Beacon Chain network (#2931)
## Proposed Changes

Add a new hardcoded spec for the Gnosis Beacon Chain.
Ideally, official Lighthouse executables will be able to connect to the gnosis beacon chain from now on, using `--network gnosis` CLI option.

799aedd631 Add default config options for transition constants (#2940)
## Issue Addressed

Continuation to #2934 

## Proposed Changes

Currently, we have the transition fields in the config (`TERMINAL_TOTAL_DIFFICULTY`, `TERMINAL_BLOCK_HASH` and `TERMINAL_BLOCK_HASH_ACTIVATION_EPOCH`) as mandatory fields. 

This is causing compatibility issues with other client BN's (nimbus and teku v22.1.0) which don't return these fields on a `eth/v1/config/spec` api call. Since we don't use this values until the merge, I think it's okay to have default values set for these fields as well to ensure compatibility.

95b3183cb4 Make /config/spec backwards compat for VC (#2934)
## Proposed Changes

Restore compatibility with beacon nodes using the `MERGE` naming by:

1. Adding defaults for the Bellatrix `Config` fields
2. Not attempting to read (or serve) the Bellatrix preset on `/config/spec`.

I've confirmed that this works with Infura, and just logs a warning:

```

ef7351ddfe Update to spec v1.1.8 (#2893)
## Proposed Changes

Change the canonical fork name for the merge to Bellatrix. Keep other merge naming the same to avoid churn.

I've also fixed and enabled the `fork` and `transition` tests for Bellatrix, and the v1.1.7 fork choice tests.

Additionally, the `BellatrixPreset` has been added with tests. It gets served via the `/config/spec` API endpoint along with the other presets.

ceeab02e3a Lazy hashing for SignedBeaconBlock in sync (#2916)
## Proposed Changes

Allocate less memory in sync by hashing the `SignedBeaconBlock`s in a batch directly, rather than going via SSZ bytes.

b656007963 Skip serializing proposer boost if null (#2899)
## Issue Addressed

Restore compatibility between Lighthouse v2.0.1 VC and `unstable` BN in preparation for the next release.

## Proposed Changes

* Don't serialize the `PROPOSER_SCORE_BOOST` as `null` because it breaks the `extra_fields: HashMap<String, String>` used by the v2.0.1 VC.

fac117667b Update to superstruct v0.4.1 (#2886)
## Proposed Changes

Update `superstruct` to bring in @realbigsean's fixes necessary for MEV-compatible private beacon block types (a la #2795).

The refactoring is due to another change in superstruct that allows partial getters to be auto-generated.

a290a3c537 Add configurable block replayer (#2863)
## Issue Addressed

Successor to #2431

## Proposed Changes

* Add a `BlockReplayer` struct to abstract over the intricacies of calling `per_slot_processing` and `per_block_processing` while avoiding unnecessary tree hashing.
* Add a variant of the forwards state root iterator that does not require an `end_state`.
* Use the `BlockReplayer` when reconstructing states in the database. Use the efficient forwards iterator for frozen states.
* Refactor the iterators to remove `Arc<HotColdDB>` (this seems to be neater than making _everything_ an `Arc<HotColdDB>` as I did in #2431).

Supplying the state roots allow us to avoid building a tree hash cache at all when reconstructing historic states, which saves around 1 second flat (regardless of `slots-per-restore-point`). This is a small percentage of worst-case state load times with 200K validators and SPRP=2048 (~15s vs ~16s) but a significant speed-up for more frequent restore points: state loads with SPRP=32 should be now consistently <500ms instead of 1.5s (a ~3x speedup).

b22ac95d7f v1.1.6 Fork Choice changes (#2822)
## Issue Addressed

Resolves: https://github.com/sigp/lighthouse/issues/2741
Includes: https://github.com/sigp/lighthouse/pull/2853 so that we can get ssz static tests passing here on v1.1.6. If we want to merge that first, we can make this diff slightly smaller

## Proposed Changes

- Changes the `justified_epoch` and `finalized_epoch` in the `ProtoArrayNode` each to an `Option<Checkpoint>`. The `Option` is necessary only for the migration, so not ideal. But does allow us to add a default logic to `None` on these fields during the database migration.
- Adds a database migration from a legacy fork choice struct to the new one, search for all necessary block roots in fork choice by iterating through blocks in the db.
- updates related to https://github.com/ethereum/consensus-specs/pull/2727
  -  We will have to update the persisted forkchoice to make sure the justified checkpoint stored is correct according to the updated fork choice logic. This boils down to setting the forkchoice store's justified checkpoint to the justified checkpoint of the block that advanced the finalized checkpoint to the current one. 
  - AFAICT there's no migration steps necessary for the update to allow applying attestations from prior blocks, but would appreciate confirmation on that
- I updated the consensus spec tests to v1.1.6 here, but they will fail until we also implement the proposer score boost updates. I confirmed that the previously failing scenario `new_finalized_slot_is_justified_checkpoint_ancestor` will now pass after the boost updates, but haven't confirmed _all_ tests will pass because I just quickly stubbed out the proposer boost test scenario formatting.
- This PR now also includes proposer boosting https://github.com/ethereum/consensus-specs/pull/2730

## Additional Info
I realized checking justified and finalized roots in fork choice makes it more likely that we trigger this bug: https://github.com/ethereum/consensus-specs/pull/2727

It's possible the combination of justified checkpoint and finalized checkpoint in the forkchoice store is different from in any block in fork choice. So when trying to startup our store's justified checkpoint seems invalid to the rest of fork choice (but it should be valid). When this happens we get an `InvalidBestNode` error and fail to start up. So I'm including that bugfix in this branch.

Todo:

- [x] Fix fork choice tests
- [x] Self review
- [x] Add fix for https://github.com/ethereum/consensus-specs/pull/2727
- [x] Rebase onto Kintusgi 
- [x] Fix `num_active_validators` calculation as @michaelsproul pointed out
- [x] Clean up db migrations

e391b32858 Merge devnet 3 (#2859)
## Issue Addressed

N/A

## Proposed Changes

Changes required for the `merge-devnet-3`. Added some more non substantive renames on top of @realbigsean 's commit. 
Note: this doesn't include the proposer boosting changes in kintsugi v3.

This devnet isn't running with the proposer boosting fork choice changes so if we are looking to merge https://github.com/sigp/lighthouse/pull/2822 into `unstable`, then I think we should just maintain this branch for the devnet temporarily.

a80ccc3a33 1.57.0 lints (#2850)
## Issue Addressed

New rust lints

## Proposed Changes

- Boxing some enum variants
- removing some unused fields (is the validator lockfile unused? seemed so to me)

## Additional Info

- some error fields were marked as dead code but are logged out in areas
- left some dead fields in our ef test code because I assume they are useful for debugging?
